APATITE
Sterling Hill, Ogdensburg,
Sussex County, NJ, USA
Large hexagonal, blue-green apatite crystals
in marble with a black mineral that superfi-
cially resembles franklinite but on closer
inspection looks more like 'hornblende'.
Very similar to the material from Hamburg. The apatite fluoresces a pale blue under short-wave UV (fluorapatite?).

ARSENOPYRITE

Silvery arsenopyrite in marble with edenite.
The look of the matrix suggests this piece
came from the old Fowler Quarry, where
sulfide minerals were fairly common, but
the detailed locality is undocumented.
